Those who opposed Ritter proposed a plethora of different solutions to the distance problem, none of them completely convincing. The modern ionic theory only emerged in the last years of the nineteenth century, so there was nearly a whole century of electrochemistry taking place without a consensus...
This very low ohmic resistance of the cell is one of the advantages of the PEM technology. A second advantage for the PEM water electrolysis is the kinetics for hydrogen evolution reaction (HER) in acidic solutions. The charge transfer overpotential (Tafel) is nearly absent and can even be ...

The pathway leading to radical products (Kolbe electrolysis) and/or cationic intermediates (nonKolbe electrolysis) is determined mainly by the substituents in the α-position of the carboxylic acid and some experimental factors. The electrolysis products of different carboxylates have been compared with...
Electrolysis is thebreaking up (-lysis)of substances usingelectric current (electro-)– hence the name. It can be done with dissolved or molten ionic solutions such as sodium chloride (NaCl) or aluminum oxide (Al2O3) to obtain the pure elements from their ions. This is very useful because...
Efficient electrolysis through comprehensive power conversion solutions The supply of hydrogen for industrial use is a major global business, with electrical power demand to produce green hydrogen expected to reach up to 4500 GW by 2050. Current hydrogen production, however, is supplied almost entirely...
Electrolysis is done in solutions, which contain enough ions so current can flow. If the solution contains only one material, like the electrolysis of molten sodium chloride, it is a simple matter to determine what is oxidized and what is reduced. In more complicated systems, like the ...
1. The most distinct difference between the proton-ion and oxygen-ion SOEC is the electrolyte-conducting ion, which further results in different working principles. In the case of the proton-ion conducting electrolyte, H+ ions/protons are transported from the anode electrode to the cathode ...
